Abstract: 938,223. Abrasive devices. REXALL DRUG & CHEMICAL CO. (Rexall Drug Co.). Oct. 30, 1959, No. 36871/59. Class 60. An abrasive device comprises a shirred abrasive strip material mounted upon a support or backing, said shirred abrasive strip material being adhesively secured to the backing along alternate fold lines of the shirred strip material with the individual shirrs thereof at least partially overlapping one another in the direction of movement of the device during use and forming a plurality of separate abrading elements constituting the working face of the abrasive device. An endless abrasive belt, Figs. 1 and 3, comprises a flexible fabric backing member 15 to which is secured by a layer of adhesive 16 a shirred abrasive sheet material 17, e.g. a fibrous abrasive-containing sheet material as in Specification 557,038. The adhesive may be permanently flexible rubber-base adhesive. The backing has a diagonal splice and the shirred material a transverse splice. In a modification, Fig. 5, the shirred material has slits 23, 24 lengthwise of the belt; the slits 23 are staggered laterally with respect to slits 24, and there are unslit regions 25. In a further modification, the shirred material consists of a layer of melted steel wool fibres preferably impregnated with rubber latex. The layer may be impregnated with thermosetting or thermoplastic adhesives, synthetic rubber latices or elastomers such as polychloroprene or silicone latices, glue, casein, hard soap and waxes or the like. In a further modification, Fig. 11, the backing is reinforced by lengthwise filaments or strands 35, 36 of high tensile strength material eg. nylon or glass fibre cording. An abrasive disc, Fig. 7, comprises an abrasive annulus 28 secured by adhesive 29 to a flexible backing 27 of vulcanized fibre, spring steel or one or more plies of rubber-impregnated sisal fibre or other fabric or material, singly or in combination. The abrasive annulus may consist of narrow strips of shirred abrasive-included fibrous sheet material mounted on the backing in concentric array or a single strip of material may be spirally arranged. An abrasive wheel or drum, Fig. 9, comprises shirred abrasive-included fibrous sheet material 33 secured by adhesive 34 to a hub 32 which may have a covering of foam or sponge rubber or other resilient material.

Filed: 1928-12-15
Abstract: 302,588. I. G. Farbenindustrie Akt.- Ges. Dec. 17, 1927, [Convention date]. Single coatings.-In adhesive strips of paper or fabric coated with gum or rubber, the side of the material not coated with adhesive is coated with a cellulose ester, mixed ester or ether-ester, of a higher fatty acid. Unrolling of a roll of the material is thus facilitated, as the sticky surface does not adhere to the reverse side of the strip. The adhesive power of the gum or rubber is not affected. Cellulose laurate is stated to be particularly suitable for the coating.

Title: Electrodialysis method and device
IPC: B01D61/46
Filed: 1963-09-25
Abstract: An electrodialysis device comprises an ion selectively permeable membrane in a sinuous path forming liquid treatment cells and means to drive the membrane along the sinuous path. A membrane may be supported at the top and bottom of a tank, Fig. 1, or at the sides of the tank, Fig. 22 (not shown), it may be anion permselective, cation permselective, or lenghts may be alternately anion and cation permselective Fig. 4 (not shown). During periods when the membrane <PICT:1062742/C6-C7/1> is not being moved, it may be tensioned either by pulling it at its end, or by holding its ends still and moving its supports apart, Figs. 6, 19 and 20 (not shown).  As shown in Fig. 1, a membrane 34 passes around rods 32 and 33 but it may pass over rollers on bars, Fig. 15 (not shown), or rollers on gaskets, Fig. 8 (not shown), or around rotatably driven rods, Fig. 7 (not shown), which may have sprockets, Fig. 17 (not shown), for engaging apertures in the edges of the membrane, Fig. 16 (not shown).  It may be in the form of a continuous loop driven by a motor, Fig. 21 (not shown). The movement may be continuous or intermittent in one direction or a backward and forward motion. The membrane movement is the equivalent of stirring the solution. Fig. 1 (and Fig. 2 (not shown)) illustrate an anion permselective membrane 34 in a tank 25 containing NaOH solution with a manifold (40) passing fruit juice such as citrus juice between pairs of vertical runs 38 of the membrane.  In operation hydroxyl ions pass into the juice and citrate ions pass out of the juice, thus reducing the juices acidity. Sponge plastic 36 extends across the bottom of the tank and contacts the membrane. Fig. 5 (not shown) illustrates an embodiment similar to that of Fig. 1 but wherein the vertical runs of the membrane are alternately anion and cation permselective, thereby providing alternate concentrating and diluting cells in the tank.  Fig. 14 (not shown) illustrates a membrane wound around gaskets (70, 81) provided with rollers 72. The gaskets (81) are identical to the gaskets (70), Fig. 8 (not shown), but are in a reversed and inverted position. They have manifold apertures (75-78) and liquid flow passages (79, 80). Apertured spacer strips, Fig. 12 (not shown), are provided between the gaskets at the edges of the membrane.  Fig. 22 (not shown) illustrates a device wherein liquid withdrawn from the tank washes the anode and cathode.

A photographic dye-diffusion transfer process giving a direct positive colour transfer image comprises exposing to a subject a photographic light-sensitive material containing a silver halide emulsion of the internal latent image type, the silver halide grains having adjacent thereto a non-diffusible colour coupler which will react with oxidized colour developer to form or release a diffusible dye, treating the exposed material with an aqueous alkaline solution in the presence of a colour developing agent and an amino hexose reductone or an anhydro amino hexose reductone as a fogging agent so that a diffusible dye is formed or released in the unexposed regions of the emulsion layer to form a positive image therein. The developing agent may be present in the light-sensitive material or in the aqueous alkaline processing solution. The reductone derivative may be present in the light-sensitive material in the emulsion or an adjacent layer or in the transfer receiving layer or in the aqueous alkaline processing solution. The transfer receiving layer may be a separate sheet from the light-sensitive layer, or it may be integral therewith and may be stripped off after processing or the developed emulsion layer may be washed off leaving the receiving layer bearing the dye image. Multicolour material having red, green and blue sensitive internal latent image emulsions each containing the appropriate non-diffusible coupler may be used in the process to give a positive multicolour image, the emulsions being arranged in separate layers or packets.

Abstract: 1468750 Automatic voltage control HEWLETT-PACKARD CO 29 Aug 1974 [17 Oct 1973] 37879/74 Heading G3R [Also in Division H2] A system for supplying a regulated D.C. voltage using pulse width modulation and having rapid response and ripple rejection includes an oscillator which predetermines the pulse frequency and a comparison circuit which determines the pulse width in response to a reference voltage input, the sensed output voltage, and an additional stabilizing voltage which may be of parabolic, sinusoidal, linear ramp, or other amplitude varying waveform. As shown in Fig. 2, a transformer 23 receives pulses from switching elements which may be antiparallel transistors, SCR's or a triac, connected to a rectified A.C. supply. The transformer output is rectified and averaged by a first filter circuit 25, 27 and then passed through a second filter circuit 31, 33 which is connected to a load 29. The final output voltage is compared with a reference voltage in a differential amplifier circuit 35 having a relatively long time characteristic so as to respond to slow variations in the load 29, and the output of circuit 35 forms a reference voltage input for a second comparator 21 which is a non-integrating circuit responsive to rapid variations in the output voltage. The other input to comparator 21 is derived from the output of the first filter circuit 25, 27 which is added to a stabilizing voltage V S  produced by a circuit 22 which forms a parabolic voltage synchronized with an oscillator 17. Pulse width modulator 19 turns the main switching elements on in response to the output of comparator 21, while the elements are turned off at a predetermined frequency by the oscillator 17. Circuit details are described briefly with reference to Fig. 3 (not shown). A current limiter (not shown) may be used to turn the main switching elements off in response to excessive current in the elements or in the choke 25.
